Title: Improvements in and relating to electric power transmission systems
IPC: H02P9/10
Filed: 1926-04-30
Abstract: 251,653. British Thomson-Houston Co., Ltd., (Assignees of Clarke, E.). April 30, 1925, [Convention date]. Systems depending on two or more machines; Regulation.-In a high voltage power transmission system synchronous condensers having highly saturated field poles are used to correct the inductive drop in the line. These condensers are employed in the vicinity of the load and at a point or points in the line as required. They are provided with automatic field current regulators. The inherent regulation of such machines acts immediately upon drop in voltage due to sudden increase of load, and before the automatic regulators can come into operation to restore the voltage, to supply a corrective reaction of sufficient magnitude to prevent a pressure drop large enough to cause instability and enables the system to be worked closer to its maximum power limit. This limit or the load at which unstable conditions will be encountered is also increased.

Title: Apparatus for co-ordinating the actions of a tape-type sound recorder and a still-picture projecting lantern
Inventor: ARTLETT-COE JOHN BURTON
IPC: G03B31/00
Filed: 1957-04-09
Abstract: 817,653. Sound and picture apparatus. ALDIS BROS. Ltd. March 21, 1958 [April 9, 1957], No. 11483/57. Class 40 (2). Apparatus for co-ordinating the actions of a tape-type sound record apparatus and a still-picture projector comprises manually operable means for perforating the tape at selected intervals in accordance with desired picture changes, and switch means controlled by the said perforations for operating a relay controlling the picture-changing mechanism. Details are given of a tape perforator, Fig. 3, wherein pressure on a lever 18 withdraws a spring-loaded arm 14 carrying a punch 16. At a given moment a pawl 20 on the lever 18 slips through a slot in the arm 14 so that the punch 16 is released to stamp a perforation in the record tape which is supported by an anvil 17. Passage of tape through the record apparatus permits contacts in the form of rollers 5, 6 to complete an electrical circuit controlling a picture slide changing mechanism, details of which are not given. The rollers 5, 6 are normally held apart in an inoperative position by a spring 8, but are brought together when a lid carrying pins 10 is placed in position. One of the pins 10 comes into contact with the spring 8 and serves to push the rollers 5, 6 together and the ends of both pins 10 also serve to close safety switches 11, 12, Fig. 7. When the contacts 5, 6 make through a perforation in the tape, a circuit from a voltage source 42, 44 is completed through a relay coil 26 to close contacts 27, 28. The contacts 28 close the supply circuit to a motor 41 operating the slide-changing mechanism, while contacts 27 complete a hold-on circuit to the relay until the slide-changing mechanism operates a change-over switch 43. At the completion of the slide-changing operation the switch 43 reverts to its former position and the motor 41 comes to rest ready for the next slide-changing initiation.

Title: Improvements in or relating to primary cells of the air depolarized type
IPC: H01M12/06
Filed: 1949-04-30
Abstract: 658,032. Primary batteries. NATIONAL CARBON CO., Inc. April 30, 1949, No. 11581. Convention date, Sept. 30, 1948. [Class 53] An air-depolarized cell comprises a casing 10 of a thermoplastic synthetic resin having in opposite walls apertures 12, 14 for the admission of air. Carbon electrodes 16, 18 are mounted on a steel or other metal support S which has two perforated plates or legs 22, 24 and is fitted with terminals 36, 38, as shown in Fig. 3. The carbon electrodes consist of carbonaceous material mixed with a resinous binder and a waterproofing agent such as oil or rubber solution and they may be moulded on to the plates 22, 24. A thin coating of thermoplastic cement is applied to the margins of the plates 22, 24, and the casing 10 is made by moulding it about the support S so that the resin of the casing and the resin on the plates 22, 24 and the resin in the carbon electrodes become integrally united and watertight joints are formed round the openings 12, 14. Within the casing is a zinc electrode 40 which is held in grooves 44, 46 in the casing. The zinc may be perforated and supports a fibrous pad 48 which is impregnated with electrolyte which also fills the casing. The pad 48 may consist of glass wool or a synthetic resin and the electrolyte may be a solution of caustic soda containing zinc oxide thickened with starch. The zinc electrode is riveted to a metal tab 50 attached to a steel or other metal plate 52 which forms a closure for the lower end of the casing which, is softened by heat and flanged over the plate as shown in Fig. 1. An air space 54 is left at the lower end of the cell. Before the cell is put to use and to prevent drying out of the liquid contents the openings 12, 14 may be covered with a removable material such as an adhesive thermoplastic tape. Bosses 60 are formed on the outer surface of the casing as shown in Fig. 2 to allow air to have access to the openings 12, 14 when the cell is placed against a flat surface.

Title: Graphic Communication System
IPC: H04N1/17
Filed: 1967-03-13
Abstract: 1,174,611. Facsimile systems. RANK XEROX Ltd. 13 March, 1967 [17 March, 1966], No. 11584/67. Heading H4F. To increase the information transmission efficiency of a facsimile communication system over a transmission link of limited bandwidth, the analogue signals derived from scanning a document are converted into digitalized or amplitude quantized binary video signals, encoded, e.g. run length coded, to remove redundancy therein, and stored in a line store from which they are read out at a rate near the predetermined maximum bandwidth of the transmission link. The document is mounted on a drum and successive groups of lines of the document are raster scanned by a flying spot cathode-ray tube scanner intermediate successive incremental rotational steps of the drum. When the line store has been partly unloaded to the transmission link, e.g. by 90% when the maximum reduction in bandwidth is 90%, a scan start signal is generated which is fed to the scanner control to allow the start of the scanning of the next successive line. Since the encoded length of a line is not the same for every scanned line, a sync. -word is added to the video pulse train between the data output for each line so that a receiver will be able to detect the beginning and end of each line. The sync.-word is fed to the line store without being encoded and is also passed to a counter, the output of which delays the scan start signal until the average compression of the scanned line corresponds to the maximum reduction in bandwidth, since if the compression factor is greater a data pile-up would occur in the line store end at the receiver. After a predetermined number of lines scanned, the scan is interrupted to allow the drum to step the document to the next scan position and the scanning beam of the flying spot scanner is vertically reset. In the receiver the video pulse train is decoded to produce the decompressed binary information signal train which is fed to a line store from which it modulates a flying spot cathode-ray tube scanner arranged to scan the surface of a zerographic facsimile printer drum which is stepped after the predetermined number of lines as in the transmitter. The sync.-word is detected after each line and used to control read-out from the line store and operation of the printer in a similar fashion as in the transmitter
Patent GB-752489-A (GB)
Title: Improvements in or relating to spring mechanisms
IPC: F16F1/02
Filed: 1954-04-22
Abstract: 752,489. Springs. ABBEY, A. (Glaser, L. B., and Votta, F. A.). April 22, 1954, No. 11630/54. Class 108 (3). [Also in Group X] A spring mechanism comprises a spring strip 40 (Fig. 7) fixed to one (41) of two relatively movable members 41, 42 which are spaced apart a distance greater than the thickness of the spring but less than the distance required for coiling of the spring, receiving means 45 provided in the other member (42) which allows a free end of the spring to coil (as at 44) when the free end engages the means 45. Thus when the spring 40 is in the position shown in Fig. 7, it can exert no force between the members. When the member 42 is moved to the right relative to the member 41, the end of the spring 40 is able to start coiling up in the recess 45. The action of coiling results in a spring force being exerted between the members 41, 42. In Fig. 7, there are two springs 40 and 43, one 43 being fully coiled when the other 40 is fully retracted, and vice versa. One spring may, however, be mounted on the member 42, its corresponding recess being in the member 41. The two springs may be replaced by a single spring anchored at its mid point to the member 41, the recesses 44, 45 being disposed respectively beyond the free ends of the spring. In Fig. 3, the members 41, 42 are replaced by members 20, 22 which have rotary, instead of rectilinear, relative movement. The spring 29 is anchored at its mid-point to the member 20. Rollers 27, 28 are provided on pins 25, 26 in recesses 23, 24 upon which the spring 29 is adapted to coil. The distance between each free end of the spring and the corresponding recess, determines the degree of free relative movement of the members, the spring action not occurring until one of the free ends picks up its corresponding recess and is so able to start coiling. Alternatively, a predetermined degree of free relative movement may be provided by making the distance between the recesses less than the length of the spring. The spring is thus coiled in both recesses when the centre of the spring is disposed midway between the recesses. The force exerted by each spring is then equal and opposite, until one spring or the other (according to the direction of relative movement) is retracted from its respective recess. The spring may be of duralumin, beryllium copper or phosphor bronze. Where two springs and respective receiving means are provided, one receiving means may be of larger diameter so as to provide a spring force larger than that of the other. The invention may be applied to sliding doors (see Group X), circuit breakers and switches, and to machines having reciprocating or oscillating control elements for changing direction.
